Vasa parrot
:''The name vasa parrot is also used for the greater vasa parrot.''
The vasa parrots (''Coracopsis'') are three species of parrot which are endemic to Madagascar and other islands in the western Indian Ocean. Some taxonomists place the genus in ''Mascarinus''.
== Taxonomy ==
There are three to four species and several subspecies:〔(【引用サイトリンク】Zoological Nomenclature Resource: Psittaciformes (Version 9.020) )
''Coracopsis'', Wagler 1832
*''Coracopsis vasa'', (Shaw) 1812 - (greater vasa parrot)
*
*''Coracopsis vasa comorensis'', (Peters,W) 1854
*
*''Coracopsis vasa drouhardi'', Lavauden 1929
*
*''Coracopsis vasa vasa'', (Shaw) 1812
*''Coracopsis nigra'', (Linnaeus) 1758 - (lesser vasa parrot also known as black parrot)
*
*''Coracopsis nigra libs'', Bangs 1927
*
*''Coracopsis nigra nigra'', (Linnaeus) 1758
*
*''Coracopsis nigra sibilans'', Milne-Edwards & Oustalet 1885 (sometimes considered a separate species the Comoro parrot)〔http://www.birdlife.org/datazone/species/factsheet/62292583〕
*''Coracopsis barklyi'', Newton 1867 - (Seychelles black parrot)
A 2011 genetic study found the Mascarene parrot from Réunion to be nested among the subspecies of the lesser vasa parrot from Madagascar and nearby islands, and therefore not related to the ''Psittacula'' parrots. It also found that the Mascarene parrot line diverged 4.6 to 9 million years ago, prior to the formation of Réunion, indicating this must have happened elsewhere. The cladogram accompanying the study is shown below:

Another group of scientists later acknowledged the finding, but pointed out that the sample might have been damaged, and that further testing was needed before the issue could be fully resolved. They also noted that if ''Mascarinus'' was confirmed to be embedded within the ''Coracopsis'' genus, the latter would become a junior synonym, since the former name is older. Hume has expressed surprise by these findings, due to the anatomical similarities between the Mascarene parrot and other parrots from the islands that are believed to be psittaculines.
